Not only in production phase, but also in prototyping phase of the NPD process, certain components of a car that may require ASTM A1011 HSLAS-F GR70 (High-Strength, Low-Alloy Steel - Formable, Grade 70) raw material include:

1. Structural Components:

• Body panels, such as the hood, doors, and fenders
• Roof structure
• Pillars (A-pillars, B-pillars, C-pillars)
• Rocker panels
• Rear quarter panels
• Trunk lid

2. Chassis Components:

• Suspension components (e.g., control arms, knuckles)
• Subframes
• Crossmembers
• Rear axle housing

3. Safety-Critical Components:

• Bumper beams
• Seat belt anchors
• Airbag housings
• Reinforcement structures within the doors and pillars

The ASTM A1011 HSLAS-F GR70 steel grade is commonly used for these components including the rapid prototype parts for design verifying due to its high strength, formability, and weight-saving properties. Take the part shown as the attached 2 pictures, this is a deep drawn prototype part, or we call it as rapid deep draw stamping prototype part, the high-strength characteristics of this GR70 steel allow for the design of thinner, lighter, and more efficient automotive structures and components, which can contribute to improved fuel efficiency and overall vehicle performance.

The specific selection of ASTM A1011 HSLAS-F GR70 for a particular car component will depend on the design requirements, such as the need for strength, crash performance, and manufacturing feasibility. Engineers and designers work closely with material suppliers, prototype supplier or mass production supplier to optimize the use of this and other advanced steel grades throughout the vehicle.
